Thirty-third Street Bridge in Philadelphia

The bridge was built in 1901 with an unusual skewed arch, and listed on the National Register of Historic Places in 1988.

Ashlar, or dressed stone, covers the exterior of the arch, but the unusual skewed ribs are made of brick.

The underpass is now inside an industrial area and normally closed even to foot traffic.

The tracks of the former Pennsylvania Railroad are located just to the north and pass under a large modern bridge on Thirty-third Street.
